the zone in which an image seen through a lens is in perfect focus
The distance along the optical axis through which an object can be located and clearly defined when the lens is in focus.
the distance along the optical axis throughout which the object can be located and yet be imaged with satisfactory clarity. This is used in stereo microscopy.
The area in which all objects, located at different distances from the camera, appear in focus. The depth of field depends primarily on the focal length of the lens, its f-stop, and the distance from the camera to the object.
the area between the nearest and farthest points from the camera that is acceptably sharp in an image
The zone of acceptable sharpness in a photo, usually extending in front of and behind a subject that is in sharpest focus.
The range of distance which is in focus. A greater depth of field results from a small camera aperture or a small pupil size in the eye.
The zone, or range of distances within a scene that will record on film as sharp. Depth of field is influenced by the focal length of the lens in use, the f-number setting on the lens, and the distance from the camera to the subject. It can be shallow or deep, and can be totally controlled by the photographer. It is one of the most creative and profound effects available to photographers.
The area of sharp focus in a photograph that becomes greater as the f-stop number is increased.
The distance in front of and behind the subject that appears to be in focus and can be altered by changing the camera’s aperture. The wider the aperture, the shorter the depth of field, and vice versa.
The portion of an image which is in focus.
The region of reasonably sharp focus in front and beyond the subject position. The boundaries of the depth of field are called the near limit and the far limit.
The area in a scene that is in acceptable focus. As aperture size or focal length increases, depth of field decreases.
The range of object distances within which objects are in satisfactory sharp focus in a photograph.
distance covered by acceptable sharpness of an image, extending in front of and behind the point of focus. Depth of field
The total distance, on either side of the point of focus, which, when viewed from an appropriate distance, appears sharp in the final print.
The sharpness and focus of the actual scene to be shot.
Refers to the area that is between the focal point and the point where the laser meets the substrate on which it is engraving. This is the area that contains the densest laser energy and is most efficient for engraving.
in photography, the area in front of and behind the focused point that is sharp. A shallow depth of field is used in portraits to provide a soft backdrop, whilst a greater depth of field is useful for landscapes to ensure everything from the foreground to the background is in focus. Shorter (wideangle) lenses and smaller apertures increase depth of field.
The area of a photo that is in sharp focus.
While a lens focuses on a single plane of depth, there is usually an additional area in focus behind and in front of that plane. This is depth of field. Depth of field increases as the iris is closed. There is more depth of field the wider the lens and less the longer the lens. There is a deeper area in focus the further away a lens is focused than there is when a lens is focused close. Depth of field does not spread out evenly; the entire area is about 1/3rd in front and 2/3rds behind the plane of focus. To factor together all these variables it is best to consult a depth of field table, such as the ones found in the American Cinematographer's Manual. [Go to source
The range of distance along the z-axis from the viewer.
Degree of focus or the zone of acceptable sharpness in television or film.
The range of distance from the camera, which is in acceptable focus. Telephotos have a small depth of field - they have sharp image resolution only at or near the point of focus. Wide angle lenses in contrast have a large depth of field - objects near and afar have acceptable focus.
A measure of how much of a picture is in focus - from the nearest point in the scene to the camera that looks sharp, to the furthermost point that looks sharp. Depth of field is dependent on iris setting, subject distance, and focal length of the lens.
In photography, the range of distances within which objects will be sharply focused. (Objects outside of this range appear blurred or out of focus.) In Maya, all objects are sharply focused by default, no matter how near or far they are from the camera. However, Maya does selectively focus on objects to simulate depth of field.
This is the difference between the nearest and furthest points in a scene that remain in sharp focus. Depth of field is dependent on the F-stop and focal length of the lens.
The distance between the closest and farthest point at which a bar code can be scanned. DISCRETE - Symbologies in which intercharacter gaps are not treated as characters.
The portion of a scene (foreground, midground, background) which appears in crisp focus when viewed through a photographic lens.
When a camera focuses on a distant object, all the objects at that distance are sharply focused. Elements not at the same distance are out of focus and will not appear as sharp in a photograph. The human eye cannot distinguish between very small degrees of "unsharpness." Some objects in front of and behind the subject may still appear sharp. Generally the closer they are to the subject, the sharper they are. Images with a "deep" depth of field tend to maximize the distance from which the auxiliary image elements can be from the subject and still remain sharply focused. Images with a shallow depth of field have a very limited range of focal sharpness. In an image with a shallow depth of field the front of a bird could be sharply in focus while the back of the bird is out of focus.
Zone from the points closest to the camera to the points farthest from the camera that are in acceptable focus.
The distance of acceptable sharpness that is in front of and behind a specific focus point. A larger aperture (lower f-stop number) results in a shallower DOF, rendering only a small amount of the scene in focus. This is useful in more artistic shots where a specific subject is to be emphasized against a distracting background. A smaller aperture (higher f-stop number) results in a wider DOF, resulting in much more of the scene being in focus.
The amount of foreground and background that is in focus at a given f-stop or aperture. Depth of field is controlled by the camera's f-stop or aperture. Depth of field is often used to blur distracting elements in the background and thus concentrate the viewer's attention on the main subject of the photograph.
The depth of field refers to the nearest and farthest points in your photograph that are in focus in your shot. A lens can only focus on one single distance fully, but with a wide depth of field, areas both closer and further from that one point are relatively in focus as well. Stopping down to a smaller aperture increases the depth of field, and will result in more of the photograph being in focus.
This refers to the area, or depth, of the photograph that is in focus. You can control the depth of field by adjusting the aperture. If the picture is in focus for a large distance between the foreground and background, then the depth of field is higher. The greatest depth of field possible is called the Hyperfocal Point. These two pictures illustrate a great depth of field and a shallow depth of field. See also: Aperture | Hyperfocal Point
Distance between nearest and farthest parts of the subject sharply imaged at the same time.
The measurements of the closest and farthest planes in front of the camera lens between which everything will be in sharp focus. A depth of field from 5 to 16 feet, e.g., would mean everything closer than 5 feet and farther than 16 feet would be out of focus.
The distance between the nearest and farthest point of a photograph. See minimum and maximum depth of field.
A specific “window” of distance in which objects remain in focus. Example – a camera’s field of view will present a picture encompassing a distance of 200 feet from the camera; objects in the picture are in focus at a distance of 10 feet to 90 feet within the picture. The window or depth of field is 80 feet for this example. The depth of field will change in relation to the change in F-stop where the depth of field increase as the F-stop increases (F-numbers get larger).
The zone of focus which is rendered acceptably sharp.
The range of sharp focus. Controlled by the focal length and aperture opening of the lens. Here's a really neat On-line Depth of Field calculator for you to play with
The amount of the picture that is in focus. Depth of field increases at smaller lens apertures (ie the larger numbers).
Depth from the focal point as affected by aperture and focal length.
Depth of Field (DOF) is the difference between the farthest scannable distance and the closest scannable distance to the barcode.
The range within which all subjects, though located at different distances from the camera, are in focus.
is the zone of acceptable sharpness in a picture extending in front of and behind the subject being focused on by the lens. A large aperture (smaller f-stop number) will give you a shallower depth of field.
The area in front of and behind the focus point that is visibly sharp. Wide-angle lenses and small apertures produce a greater depth of field. Telephoto lenses and large apertures give shallow depth of field.
The range of sharpness in front of and behind the subject or object focused on.
A photograph that shows the area close to the camera and things far away all in good focus is said to have a large depth of field. A narrow depth of field is when only a thin section of the scene, say from ten to twelve feet away from the lens, is in focus.
This is the distance between the closest and farthest points that appear to be in good focus in a picture.
The area between the nearest object in focus and the furthest object in focus.
The amount of a photographic image that is in focus in relation to the distance from the camera. Depth of field is affected by the aperture and focal length of the lens, and the distance of the subject from the camera.
A measure of how much, and what depth, of the image is in focus.
Refers to the distance between the closest and farthest sharp or in-focus portion of a photograph (also called the focal range). A large depth of field means that a large area both in front and behind your main subject will appear sharp. A shallow depth of field implies that anything other than your main focus point will appear blurred. A smaller f-stop (F2) will create a shallow depth of field. A larger f-stop (F11) will create a greater depth of field. A picture taken with the camera set to F8 A picture taken with the camera set to F2
Optics will focus at some specific distance. The depth of field will indicate how well a specific part of a picture will focus by how far it varies from the focal point.
Detail in front of and behind the point of optimum focus that gives a zone of acceptable sharpness.
The range in front of the lens with acceptable focus.
The area in front of the camera, measured front to back, which is in focus.
Front to back area in the camera view which is in focus. The better the lighting, the greater the Depth of Field possible.
indicates how much of a scene will be sharp and in focus. With a greater field of depth more objects in the picture will be in focus. A smaller depth will allow you to focus on the subject of the picture and have it stand out from the background.
Distance between nearest and furthest point which are in focus
The distance between the nearest and the farthest points in a picture that are reasonably in focus. The depth of field can be manipulated using different kinds of lenses and exposures.
The in-focus range of a lens or optical system. It is measured from the distance behind an object to the distance in front of the object when the viewing lens shows the object to be in focus.
The distance from the front of the viewable area in focus to the back. Depth of field increases with improved lighting.
Refers to the distance at which 3D objects are drawn in the distance. Closer objects are rendered more carefully and precisely than objects further way, which can be blurred and less precise. The scale at which object's precision is based on the depth of field setting.
Photographer term for relative sharpness of features in an image regardless of their distance from the camera when photographed.
The area in front of and behind the object in focus that appears sharp on the screen. The depth of field increases with the decrease of the focal length, i.e., the shorter the focal length the wider the depth of field. The depth of field is always wider behind the objects in focus.
The area within which objects are in focus; a large depth of field allows a great range of objects to be in focus simultaneously, while a shallow depth of field offers a very limited area in focus. Depth of field normally depends on how far "open" a lens is (a lens works much like an eye, with the pupil opening or contracting to control light). An "open" lens (for example, f 1.4) creates a shallow depth of field while a "stopped down" (contracted) lens (for example f 16) creates a large depth of field.
The distance between the maximum and minimum plane in which a code reader is capable of reading symbols of a specified X dimension.
Depth of field (DOF) Range of focus. Controlled by the aperture value of the lens. Large aperture yields shallow DOF. Small aperture yields deep DOF.
The measurement of the area in front of and behind the subject that is in focus.
The portion of a picture between the camera lens and infinity which is in focus
The measurements of the closest and far thest planes in front of the camera lens between which everything will be in sharp focus. A depth of field from five to sixteen feet, for example, would mean everything closer than five feet and farther than sixteen feet would be out of focus.
The proportion of the field of view that is in correct focus. The depth of field in focus DECREASES when: the focal length is longer, the f number is smaller, or the object distance is shorter.
Measure of the range along a camera's line of site in which objects will be in focus.
A measure of the area of an image that is in focus, measured as the depth from the focal point of the image.
the distance in front and behind the subject which is in acceptable focus. One third of it is in front of the subject actually focused on, two-thirds behind. How much depth depends on the focal length of the lens, the actual distance focused on and the size (f-stop) of the aperture. The greatest depth of field is produced at the shortest focal length, and the smallest aperture.
The area in focus in front of and behind the subject.
The distance from the furthest to the closest points in a photograph that are in focus. Depth of field is controlled by the size of the aperture being used. By adjusting shutter speed to compensate for a narrow aperture, depth of field can be increased. A larger opening in the lens will decrease depth of field.
The area on either side of the plane of focus that is in acceptable focus. The part of an image, from foreground to background, that is in acceptable focus. It is a function of aperture size, subject magnification and camera to subject distance.

The distance between the furthest and nearest points of the subject you are photographing that are sharp. Generally speaking this is one third in front of the subject and two thirds behind.
The distance between the maximum and minimum surface in which a scanner is capable of reading bar codes of a specified X dimension.
The range in front of and behind the point of focus where objects will appear to be in focus. The depth-of-field becomes narrower with a larger aperture (lower f-number), longer lens focal length, and shorter distance between the camera and subject. focal length PART 2-07
The distance range from the camera to the nearest and farthest points in a scene that are in sharp focus. Use the aperture to determine the depth of field, the smaller the aperture (f11, f16, etc) the longer the depth of field.
this describes what is in focus in front of and behind the object on which the lens is focused.
defined by the strength of a lens: the greater the strength of the lens, the more confining the depth of field; a critical issue to know about when learning to use "low vision aids".
The range of an imaging system in which objects are in focus. Measured from the distance behind an object to the distance in front of the object with all objects appearing in focus.
in a photograph, the range between the nearest and the farthest things that appear in focus in a photograph
The distance between the objects nearest and furthest from the camera that will be in acceptably sharp focus.
The zone of acceptable sharpness in front of and behind the subject on which the lens is focused; extends approx. one-third in front of and two thirds behind the in-focus subject; dependent on three factors: aperture, focal length, and focused distance; the wider the aperture, the longer the focal length, and the closer the focused distance, the less the depth of field, and vice versa; in comparison to a normal lens, wide-angle lenses have inherently more depth of field at each f-number and telephoto lenses have less.
The distance between the nearest and furthest objects in a photograph that are considered to be acceptably sharp. Dependant on aperture, focal length and focused distance. The smaller the aperture, the wider the lens and the further the focused distance, giving a greater depth of field and vice versa.
The working range of the beam in or near the focal plane of a lens; a function of wavelength, diameter of the unfocused beam, and focal length of the lens.
This is the distance at which the camera is in good focus. This distance is a factor of the lens used. Varifocal lens allow for the user to set this distance. Generally this should be set in dim light to get the best balance between day and night. Use of a Neutral Density filter can make this easier.
The range of distance in a scene that appears to be in focus and will be reproduced as being acceptably sharp in an image. Depth of field is controlled by the lens aperture, and extends for a distance in front of and behind the point on which the lens is focused.
The area of a photograph that is in focus.
The difference between the closest and farthest distances an object may be shifted before an unacceptable blur is observed at a particular resolution.
The distance between the farthest and nearest points which are in focus. DOF varies according to numerous influencing factors such as lens focal length, aperture and shooting distance.
The range between the maximum and minimum distance from which a symbol can be read.
is the distance between the nearest and furthermost points of the scene which appear in sharp focus. It depends upon the F-stop and focal length of the lens.
Range in front of a camera's lens in which objects appear in focus. Varies with subject-to-camera distance, focal length of a camera lens and a camera's aperture setting.
Depth of field (also known as depth of focus) refers to the range of distance from the camera that is in good focus. The smaller the aperture of the lens, the longer the depth of the field. However, less light coming into the lens, means that the image will be dimmer, so the camera needs to compensate by increasing the gain. For example, the best (longest) depth of the field would be obtained on a bright, sunny day with a very small aperture on the camera. In this case the imaging device still gets a reasonable amount of light, even with a small aperture. The worst (shortest) depth of field would be in a dark room, with a large aperture. The improve depth of field, the best approach is to increase the amount light on the subject, or use a more sensitive camera.
The length of the area where objects stay in focus. Depends on aperture and focal length. In wide angle shot depth of field is longer than with tele lens, and when you open the aperture, the depth of field becomes shorter.
The distance in front of and behind the point of sharpest focus that is still acceptably sharp. The larger the aperture of a lens, the less depth of field, while wide-angle lenses offer greater apparent depth of field.
Area in which all objects, located at different distances from the camera, appear in focus. Varies with subject-to-camera distance, focal length of camera lens, and camera's aperture setting.
The distance between the closest and farthest objects in focus within a scene as viewed by a lens at a particular focus and with given settings. The depth of field varies with the focal length of the lens and its f-stop setting or NA (numerical aperture) and the wavelength of light.
Area of view that is in focus. This decreases as the lens aperture opens.
The distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. Depth of field depends on the lens aperture, the focal length of the lens, and the distance from the subject.
The regions in front of and behind the focused distance where the image remains in focus. With a greater the depth of field, more of the scene near to far is in focus. Lens aperture and scene lighting will greatly influence the D.O.F.
The front to back zone in a field of view that is in focus in the televised scene. With a greater depth of field, more of the scene, near to far, is in focus. Increasing the f-stop number increases the depth of field of the lens. Therefore, the lens aperture should be set at the highest f-stop number usable with the available lighting. The better the lighting, the greater the depth of field possible. In other words, the depth of field is the area in front of the camera that remains in focus. The larger the f-number the greater is the depth of field.
The range of objects in front of a camera lens which are in focus. Smaller f-stops provide greater depth of field, i.e., more of the scene, near to far, will be in focus.
In optics, particularly photography and machine vision, the depth of field (DOF) is the distance in front of and behind the subject which appears to be in focus.
That area of an image which appears to be in focus, affected by both the aperture and the focal length of the lens. Image sharpness is not absolute but depends on, for instance, magnification and viewing distance. Depth-of-field calculators affixed to lenses should be regarded with scepticism. An image is always sharpest at the point on which the lens is focused, and stopping down increases the depth of the in-focus area only up to a point. In gravure the depth of field occupies a special position, since the impression of softness, of being out of focus, tends to become enhanced in the process.
The range that shows clarity closest to and farthest from a lens at sharpest focus. The range increases as the lens aperture is reduced or the lens angle is widened.
The amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in an image. Depth of field depends on the size of the aperture, the distance of the camera from the subject, and the focal length of the lens. The bigger the aperture, the greater the depth of field
The area in front and behind the main subject of a photograph that remains in focus; can be affected by aperture, distance to the subject, and focal length.
The minimum/maximum distance a bar code can be read using a CCD or Laser scanner.
the range of distances from the lens that will be in sharp focus. DOF is determined by the reproduction ratio of the picture and the aperture of the lens. Higher reproduction ratios result in shallower DOF, as do wider aperture seettings. Smaller apertures result in greater DOF.
Refers to the area between the point closest to the lens that is in focus and the point farthest from the lens that is also in focus.
The distance between the nearest and farthest points that appear in acceptably sharp focus in a photograph. Depth of field varies with lens aperture, focal length, and camera-to-subject distance.
The range of object distances which are in focus around a set focus distance value (object space distance).
The are in which all objects picked-up by the camera lens appear in focus. Depth of field depends on subject-to-camera distance, focal length of the lens, and f-stop.
The zone in the front and back of the are focused upon that will remain in focus. Anything within this depth of field will appear sharp. Depth of field has the following features: 1. Larger F-numbers give greater depth of field. The more the iris is stopped down the greater the depth of field. 2. Shorter focal lengths give greater depth of field. 3. Greater subject distance gives greater depth of field. 4. Depth of field is greater behind the subject than in front.
distance between the nearest point and the farthest point in the subject which is perceived as acceptable sharp along a common image plane.
This term refers to the range of distance in an image that is in focus and will be in focus on the actual photo. You can control the depth of field with the camera's lens aperture.
The working range of the focused beam. It is determined as a function of wavelength, diameter of the unfocused beam, and the focal length of the lens. A shorter focal length produces a smaller depth of the field.
The distance through which a viewed object can be maintained in relatively sharp focus.
When focused on a subject, there are areas in front of and behind the main subject where details are sharp. This area is referred to as depth of field. When the image area is narrow, it is expressed as shallow depth of field. When it is wide, it is called deep depth of field. A wideangle lens will deliver deeper depth of field compared with a telephoto which delivers a shallow depth of field. Depth of field is also controlled by the aperture. The depth of field becomes shallower as the lens aperture is shifted towards full open aperture. It becomes deeper when the aperture gets closer to the fully stopped down position.
The distance in front of, and behind, the subject that will be acceptably sharp. This distance will increase as the lens aperture is reduced.
The distance between a minimum and maximum plane in which a reader can read symbols of a specific dimension.
Depth of field is the amount of sharp detail you set between the foreground and background parts of your picture. You need to pick out the most important bit to focus on then decide how much sharp detail you want to show around it. Smaller f numbers give less depth of field and bigger f numbers give more depth of field.
Depth of Field refers to range of distances such that elements are in focus. An image with a narrow depth of field has a very small amount in focus. An image with a large depth of field has a lot in focus.
The area of sharp focus on a photograph. There are three contributing factors: the aperture or ƒ stop on the lens, the distance between the camera and the actual point of focus and the focal length of the lens.
In optics, particularly film and photography, the depth of field (DOF) is the distance in front of and beyond the subject that appears to be in focus. There is only one distance at which a subject is precisely in focus, but focus falls off gradually on either side of that distance, and there is a region in which the blurring is imperceptible under normal viewing conditions.
